Step 1

For the sour cream cake: Preheat the oven to 350 degrees F. Grease three 6-inch cake pans with cooking spray.

Step 2

Combine the flour, baking powder and salt in a large bowl. Reserve.

Step 3

Combine the butter and granulated sugar in the bowl of a stand mixer fitted with the paddle attachment. Beat until light and fluffy. Turn the mixer off and scrape down the sides of the bowl.

Step 4

Beat in the eggs, one at a time. Slowly add the vanilla, milk and sour cream. Scrape down the sides of the bowl as needed. With the mixer on medium speed, gradually mix in the flour.

Step 5

Divide the batter evenly among the cake pans and bake until a toothpick inserted into the middle of a cake comes out clean, about 20 minutes. Let cool completely on a wire rack.

Step 6

For the cream cheese icing: Beat together the cream cheese, butter, powdered sugar, vanilla and lemon juice in a stand mixer or with a hand mixer until light and fluffy. Spread icing on each layer, stack layers and cover with icing.
